  1. Oh no, not this again. on Would a National Biometric Authentication Scheme Work? · · Score: 5, Insightful

    Biometrics is inherently flawed as an authentication system, because biometrics is a password you can't change. Once someone gets your password, or at least the numerical representation of it such as could be lifted from a compromised reader or database, you are toast. How are you going to change your retina scan to something new?

    And never mind the demonstrated hackability of all but the premium readers.

    Biometrics sound great at first blush, and to the common voter they seem foolproof, so this fad will get worse before it will get better. In fact, the authentication issue may have achieved the level of complexity as the net-neutrality issue, such that Joe Registered Voter cannot possibly understand it (even if he is the rare sort to spend an hour googling it before forming an opinion).

    Meanwhile, text passwords plus certificates (where 'certificate' could be a smart card, or your cellphone's IMEI, or whatever) is still the answer for security. It's awful, to be sure, but it's much less awful than biometrics.

  3. Re:Shiny Disco Balls? on Single Photons Bounced Off Orbiting Satellite · · Score: 1

    essentially a space-based disco ball
    Shiny disco balls anyone?

    You laugh, but this was a tricky achievement. The satellite doesn't have an infinite number of reflecting surfaces. Therefore, a single photon fired at it must not only hit the satellite accurately, but it must be lucky enough to strike a reflecting surface that happens to be at the precisely correct angle. If the angle of incidence is not 90.000 degrees, or whatever exact precision, then the photon will miss the receiving antenna back on the ground.

    Since the transmitter can't control the satellite's attitude, it would've had to have fired a stream of single photons at it, patiently waiting for one to get a lucky angle of incidence and thereby make it back home.

    So, the overall achievement is both larger and smaller than the headline suggests: they had to get the angle ridiculously perfect, but they also had to fire a vast number of 'single' photons in order to do so.

    "So", said Arthur, hoping he wasn't sounding ridiculously obtuse, "why don't people get rid of the lizards?"

    "It honestly doesn't occur to them", said Ford. "They've all got the vote, so they all pretty much assume that the government they've voted in more or less approximates to the government they want."

    "But", said Arthur, going for the big one again, "why?"

    "Because if they didn't vote for a lizard", said Ford, "the wrong lizard might get in."

    Fascinating. I just realized what this means: democracy is a free-rider problem. No one will vote to install a proper candidate because everyone is afraid that the other side will then win the right to install their preferred flavor of fascist. Under the threat of a fascist, the safest thing to do is install a fascist who will reward one's political group at the expense of the others.

    Only if we could all agree ahead-of-time to *not* vote fascist, could we kick all the lizards out.

    That will never happen, because the payoff for being a free-rider depends on how many other free-riders there are. The fewer the hawks, the bigger the payoff for being a hawk. That is to say: if everyone else elects for their congressman a dove, willing to forego pork for his district in the hopes that *everyone* will forego pork for his district, willing to stop passing controls against the other side in the hopes that *everyone* will forego controls on their opponents, then the payoff is huge for the one guy who *does* grab all the pork and pass the controls.

    I always knew democracy was doomed to a death-spiral of spending and controls, but now I finally see why it's unavoidable. Free-rider problems normally can only be solved by state intervention -- and there is no state intervention when the state itself is the one caught in a free-rider problem.

    As far as I can see of how people actually use the terms 'cult' and 'religion'...

    • It's a cult if its founder is still alive, or is recently dead.
    • It's a religion if the founder has been dead so long that his adherents have had time to rewrite his character.
    • (In no case is any of it rational, practical, or efficient. Religion is for those who are insufficiently honest to build their own philosophy.)

    A cult, in other words, has elements of personality-worship in it. Religions are old enough to claim that the founder's personality could not have unduly influenced their membership.

    This is why Mormonism, whose founder Joseph Smith is now dead ~140 years, is finally shedding its cult status.

  12. Re:forced to deliver early, for political reasons on US Virtual Border Fence Doesn't Work · · Score: 1

    And you do know that SDI was a pipe dream that tricked the Soviets into a defense spending contest that basically collapsed the Soviet empire and caused the breakup of the USSR? It was never designed to be a working solution. And shooting down one of our own satellites is a far stretch from the "global missile defense blanket" we were promised. From all the test results at trying to take down actual missiles, they had a very poor success rate. And they were talking about using satellite mounted mirrors/laser system to blast down missiles. Where is that? I'd also be willing to wager that advancement in the technology field and computers are more responsible for us being able to hit fast moving targets with our missiles than the SDI research.

    The new Block III version of Patriot MIMS is directly derived from SDI's ERINT project. SDI developed the "hit to kill" technology, and Patriot III uses it (as does the Standard missile used to hit the satellite the other day). It is superior in every way to the old blast/frag warheads that earlier Patriots (including those used in Desert Storm) fielded.

    Indeed, the smaller faster nimbler warheadless Block III missiles are one quarter the size of the prior versions, and so a Patriot quad box launcher now carriers sixteen hot rounds, rather than four.

    More generally, your criticism of SDI for a putative absence of direct applications is like criticizing the Apollo project for an absence of direct applications. There is no way to monetize the act of moving the state of the art forward... but this is Slashdot, right? I thought we all understood this.

    People who are deeply religious and who hold fundamental beliefs without any basis of evidence are not rational. And while it might be fair to say they are irrational in this one sphere of discourse, that is basically the same as saying they are functionally schizophrenic. It would be more accurate simply to say that people can be articulate without being rational. Just because a person is intelligent enough to coherently express their thoughts, as your deeply religious friends no doubt are, that says nothing about the quality or rationality of those thoughts. It is quite possible to thoroughly and eloquently articulate extremely poor, utterly irrational ideas - just ask Hitler or Bin Laden.

    Well said.

    Let me add another car to your train of thought:

    People who renounce rationality, are stuck with only one method to judge the truth of others' ideas: by judging the speaker's articulateness.

    That is why scientists need not (and usually are not) articulate: in the rational realm, it is a secondary skill. It is certainly useful, but it isn't a requirement. Not so with the irrational realm: preachers et. al. need eloquence as a primary skill, because that is how their audiences judge the truth of their words.
